Figure 5.11 Flowchart. Example Crash Tree Analysis
Figure 5.11 is a flowchart depicting the characteristics of urban crashes. The highest level shows total number of all crashes and the total number of fatal and severe injury urban crashes. The next row down shows the total number of all crashes and the total number of fatal and severe injury urban crashes by mode (i.e. pedestrian, bicycle, motorcycle, commercial vehicle, single vehicle and two or more vehicles). In the next row, bicycle crashes are highlighted. The tree shows the total number and total number of fatal and serious injury bicycle crashes on each type of functionally classified road (i.e. local street, collector road, minor arterial, principal arterial, and interstate). Finally, the bicycle crashes by facility type are subdivided into crashes at intersections or on segments.
